High speed: recommended if you have high-speed Internet (DSL, cable modem) or are connected to an institutional network. Viewing in high-speed mode may cause occasional jerky images and sound interruptions if the speed of your connection is not fast enough.

If you're not sure which speed to use for viewing the films, try high speed first. If the results are not satisfactory, switch to low speed.
